How do you know what size breast shield you need?

I read on here that having the right size would increase milk output - so I got to thinking mine (came with pump) are a snug and maybe that would make a difference. But how in the world do I know what I need? Just trial and error and wasting $$? I do fine producing milk, but if there's any chance this could make a difference, esp now that I am using BM to mix with cereal, I would def. like to produce more when pumping.

Good question, I was wondering this myself! My areola barely fit into the horns and I have sort of maneuver them in.

There are pictures on the Medela site...

although I still don't know if mine are right

I keep feeling mine are wrong, but I think it is based on your nipple. I could be very wrong!

here is one web site:

I'm thinking I'm just going to have to buy a few sizes and try it.

To determine whether you think you might need a Large or Extra Large breastshield, look at your nipple as it is drawn into the tunnel of the shield during pumping. It should move freely and easily, and should not rub against the sides of the tunnel. If the breastshield fits tightly, your nipple will rub against the sides of the tunnel with each vacuum movement of the pump. After several pumpings, you may notice that the outside of the nipple (rather than the nipple tip) is tender or sore. You may also see a little ring of skin flecks in the tunnel of the breastshield after you pump. While a little circle of milk in the tunnel is normal, a ring of skin flecks probably indicates that the tunnel is too small, and that you would be more comfortable with a larger breastshield. When your nipple moves freely in the tunnel of the breastshield, you will also note a gentle pulling movement in the areola each time the pump cycles. If you do not see any movement in the areola with the pump vacuum, the breastshield is probably too small.

Thanks for posting that - I guess I've been using the wrong size for almost 2 yrs My poor nip is sucked in there like it's in a vacuum hose

In my case, it was trial and error. I thought I would be fine with the shields the pump came with since I am a member of the IBTC After a few times of pumping and developing blisters , I went up one flange size. Let me tell you, it made a world of difference! I was able to produce more milk because I was more comfortable!!
